He was on his way to meet John Lennon ... selling the Mayfair frame as he couldn't bear the thought of profiting from Lennon’s death. He has no idea why Lennon liked his eyeglasses so much ...

The John Lennon-style glasses were handed to the man, who was with his girlfriend, in 1968 and are expected to fetch £2,000 to £3,000. It is not clear who they belonged to at the time.
